Gear honing machine tool without axial feed and gear honing method

Abstract

The invention discloses a gear honing machine tool without axial feed and a gear honing method. A left tooth face honing wheel is fixedly connected with a thread at the tail end of a left tooth face honing wheel transmission shaft through a cone hole of the left tooth face honing wheel by means of a first fastening nut; a right tooth face honing wheel is fixedly connected with a thread at the tailend of a right tooth face honing wheel transmission shaft through a cone hole of the right tooth face honing wheel by means of a second fastening nut; a machined gear is placed parallel to a work table, and two cooling hoses are placed close to a grinding area. The left tooth face honing wheel and the right tooth face honing wheel are meshed with the machined helical gear, and the honing qualityand the honing allowance of the honing wheels for the machined helical gear are controlled by adjusting the rotating speed of two servo motors and the relative phase angle phi of the two servo motors.The gear honing machine tool is a special machine tool for finish machining of cylindrical hardened helical gears produced in batches or in large quantities. Compared with other similar machine tools, the gear honing machine tool has the advantages of simple mechanism, convenient operation, and low cost of manufacturing and later maintenance.

Description

technical field [0001] The invention relates to a device and method for finishing large-size involute cylindrical helical gears, in particular to a machine tool and method for honing large-size involute cylindrical helical gears with external meshing without axial feed. Background technique [0002] Gear honing is a common method for finishing hardened gears. The cutting amount is removed by means of the pressure and relative sliding friction between the honing wheel coated with abrasives and the tooth surface of the honed gear. Common gear honing methods include external gear honing, internal gear honing, and worm honing. The most common form is external meshing, which is processed in the "free meshing" process. It has the outstanding advantages of low cost and simple equipment, but the tooth shape and tooth direction errors are large, and the ability to correct tooth shape errors is weak, which makes it difficult to improve the precision of gear processing. However, the a...

It has the outstanding advantages of low cost and simple equipment, but the tooth shape and tooth direction errors are large, and the ability to correct tooth shape errors is weak, which makes it difficult to improve the precision of gear processing

However, the above shortcomings can be overcome by using a honing machine tool with a forced transmission chain, such as Fasil in Switzerland. Reishaur's CNC internal gear honing machine has strong error correction capability, superior performance and high productivity, but the use of internal gear honing wheels for honing requires the machine tool to have large precision bearings and advanced multi-axis linkage CNC system, which makes the manufacture of machine tools extremely complex and expensive, and the maintenance cost remains high
